Examining silencer geometries

It is essential to keep noise levels in your industrial facilities under control. Failing to do so will lead to many issues later on, some of which are permanent. To prevent such situations, you may need to attach silencers to your machinery. Our speciality is designing these products. We offer steam vent silencer designs and various others, catering for many different noise sources.

A vital consideration

The pressure drop vs insertion loss equation has plagued silencer manufacturers for years. As time has passed, experts have developed standard silencer geometries. Their purpose was to deal with this equation. With backing thanks to a great deal of development and testing, you can apply these designs on an application specific basis. So, you can pick the most suitable unit for your needs. You will be able to obtain the necessary acoustic performance at a rational pressure drop.

Such designs get labelled based on a particular velocity profile. However, you are able to introduce them to a broader array of velocities. All you have to do is ensure you take an acceptable pressure drop into account.

Now that we have had a look at all of this, let’s explore the standard silencer geometries.

Low velocity

Firstly, we have a design that can provide a big pressure drop. Such geometry supplies an extremely high level of acoustic performance. But, when velocities go past 1000 FPM, pressure drop levels can become unsuitable for most situations.

Medium velocity

This is the best all-round performer the silencer market has. The straight through parallel entrance supplies a high degree of insertion loss. At the same time, the tapered tail discharge functions to keep pressure drops to a minimum.

With such a model, it is possible to work through a series of applications from 0-2000 FPM. You can get a reasonable degree of pressure drop for most of them.

High velocity

Here is a design that lets you reach into the 2000-2500 FPM range with a normal product offering. It can do that while you supply outstanding sound attenuation and lower pressure drops in comparison to the other two designs.

Another use of this design is in lower velocity projects that need very low pressure drops. At times, they can go as low as 200 FPM.
